HEEL-NIAI'LING MACHINE.

SPECIFICATION forming part of Letters Patent No. 252,215, dated January 10, 1882,v

Application tiled October 15, 1831. (No model.)

To all whom/t may concern:

Be it known that I, HENRY A. HENDERSON, of Lynn, in the county of Essex and State ot' Massachusetts, a citizen ofthe United States,

have invented a certain new and useful Improvement in Heel-Nailing Machines, ot' which,

the following isa full, clear, and exact descrip,- tion, reference being had to the accompanying drawings, forming a part of this specilication, in .explaining its nature, inl which-f Figure 1 is afrontelevation of my machine; Fig. 2 is a vertical longitudinal section thereof.v

Fig. 3 is a detail view, representing the construction of the last employed in connection with thejack. Fig. 4 is an enlarged view, representin g the upper part, or that portion ot' the machine carrying the awls, drivers, &c. Figs.

5, 6, 7, 8, 9, and are detail viewsherein`after more fully specified. f

The invention comprises a jack for holding and presenting the workto the nail-driving devices, an iron last of novel construction used in connection with the jack for supporting the work, and nail-driving devices consisting of a revolving head carrying two or three arms, as

- the case may be, one ot' which armssupports a gang or group of awls, thesecond a gang or group of drivers,and the third a device for holding the top lift of the heel. The revolving head is supported by a cross-head, which is lowered ordepressed by means of a crank and suitable connecting mechanism, as hereinafter described, and raised by suitable springs.

It also consists in a novel arrangement for feeding the nails to a position `under the'drivers, which, together with the templet t'or the awls, is supported independentlyuot' thelcrosshead, butwhich is 'adapted to be moved therewith, as hereinafter specified.

It furtherconsists in various details of con struction, which will hereinafter be more fully specified.

A representsthe lower portion of the frame.

l by. a spindle, 118, which is fastened in a hole in plate a, one of these ways being Shown in Fig. 2.

Nomeans for operatingthe carriage by power are shown; but any ofthe well-known constructions may bc employedV for this purpose.

which isa hollow post; and a rod or support,

.thumb screw or wheel 11, is arranged within Athe post, to be moved vertically by said screw The carriage supports the jack-Standard 11, 5

and wheel, and carries or supports at its up- 6o per end the metallic last form or support 115, although it may be used to receive an ordinary iron or wooden last. The last or support- 115 shown and described, however, has one or two advantages over the ordinary metallic last, in that it can be used for rights .and lefts and `can be adjusted to varying length-sizes. This I accomplish` by making the lasts or supportsgin two parts, 116 117, and connecting them the part blby `afselJ-s'crein 11, orany other suitable locking mechanism.

tion on the spindle 118, and it is shaped in such The part 117 is ar- Aranged to swivel or turnfreely a half-revolua manner .that when in the position shown in Fig. 3 it serves as a leftlast, and when turned a half it will serve as a right last.

By moving the spindle 'in or outin its hole of course the last or form may be shortened or lengthened as desired. Suitable stops may be arranged upon the spindle for preventing the'part 117 from falling or turning by gravity beyond the position which it should occupy. i

The head C, carrying the nail-driving appli- 8,5 Y

ances, is, pivoted `at c to the cross-head C', (best shown in Fig. 4,) and has the awl-carryin'g arm c', the driver-rod-carryin g arm c2, and the arm c3, which Supports the device for holding the lower lift ofthe heel, or, as I shall calll it here.-

iIiafter, the top-lift, it being the last orup'- per lift 'applied to the heel when it is in its inverted position upon the-last.

The head is keyed to the shaft c4, and this shaft has suitablel bearings, c5, in the head C',

,andat its front end Vthere is secured. a three-` `armed handle, 06,(Shown in :Figsdfand 2,)

wherebythe head may be revolved.

Each arm of the handle is provided with a notch, 0"', into which the catch c8 on the end ot' the lever c, pivoted at 010 to a suitable bracket, is closed automatically by the' spring c when the head has been revolved sufficiently to bring the notch in line with the catch.

The head is reciprocated by means of th rods D D', (shown in Figs. 1 and 4,) the crossbar D2, the loose connecting-rod D3, the crank D4 on the shaft d, and the springs d d2, the cra-nk and connecting devices servingto depress or draw down the cross-head against the stress of the springs d' d2, and the springs serving to automatically return the cross-head to its original place.

A loose connection of peculiar construction is provided between the connecting-rod DS-and the cross-bar D2, by which an automatic stopmotion is provided. To understand this it must be borne in mind that the connectingrod D3 is not attached at its lower end to the crossbar D2, but is arranged to move or swing freely at its lower end, and thatV` it communicates motion to the cross-bar D2 only when it isr permitted by themovement ot' the latch d", as it may becalled, to swing in over the top ofthe post or protection d5, which extends upwardly from the cross-bar D2 at its highest position, so that upon the continued revolution of the crank the connecting-rod forces the cross-bar and mechanism attached thereto downward.

It will be observed that the connectingrod proper ends at thev line X, and that the strapplates X', bolted to the rod, extend below this line and straddle the bar D2; also that thel latch d4 and projection d3 on the connectingrod prevent the rod fromv swinging Yover the post so long as the latch is in its normal position, but that upon the horizontal movement ofthe latch out of the path of the movement of the projection the ro'dswingsoris drawn in by the spring d when the crank is at its highest point, and then moves down upon the post engaged with it and forces itand bar D2 and connecting devices downwardly.

In Fig. l the connecting-rod is represen ted. as disengaged from the post and at its lowest position. d?, which .has a horizontal sliding movement in suitable ways at right angle Vto the line of revolutionl of the crank, and in Fig. 2 I represent a lever, d", connecting rod C19, and spring d10 Ifor giving this latch the proper movements in relation yto the projection d3. The latch is quite narrow, and when at rest acts,.as above stated, as an obstruction in preventing the con- When, however, it is desired to start the machine, the lever d. is drawn out and the latch moved from .the path of the projec-l tion d3, which, by the spring d6, with the connecting-rod D3, is drawn to a position over the block di". of the crank the connecting-rod is givena downward movement, and Aof course moves the post and cross-bar D2down with it. Meanwhile, the

The latch d4 is supported by a bar,

Then by the continued revolutionV handle d8 being released, the latch d4 is auto. matically drawn back to its original position by the spring d10, so that during the upward movement ofthe projection d3 its side surface comes in contact with the side surface ofthe latch, and the connecting-rod is thereby moved oft' the upper surface of the post to its original position, and kept oli' thereby until it is again desired to start the machine. A

The shaft d has suitable bearings in the framevot' the machine, and is revolved in any desirable manner.

E represents the gang or group of awls. They are fastened to their supporting-block 6 at the endot the arm c in any desirable way, land the block is fastened to the end of the arm in any suitable manner. In Fig. 2 they are represented in a position to be immediately driven. e represents the templet, which -is provided with holes a trilie larger than the size A ofthe awls and drivers. It is supported at the end of the plate e2, which is pivoted at c3 to the yielding post e4.

The post, it will be observed, is arranged at the left hand of the machine, and the templet n is swung or moved horizontally upon a vertical axis into position, and is located in that position by means of a pin,e5, and latch c6, adapted to close automaticallyover the pin loyspring-V pressure. supports a plate, c7, which is pivoted thereto at e8, and which carries at its end the nail holder e9. This nail-holder is adapted toY be swung out from the templet plate, as represented in Fig.v 2, and its under surfaceis -recessed to receive a sliding plate, @10. ThisA plate has a limited extent of movement, is provided with holes corresponding in number, position, land size to the holes in the templet and nail-holder, rand has a downwardly-projecting The templet-plate c2 also carries or IOO IOS

Suitable .grooves or guides on or in the under surface ot' the nail-holding block yare `arranged vfor receiving the sliding plate, and need `not further. be described.

Avprojection, 612, vacts as a stop in preventing the plate from being withdrawn too farin.

moving it to close the holes in the nail-holder. The templet and the nail-holder may be,

locked together vby any suitablev latchingrde-V vice. v vAn adjustable stop, el, fixes the extent of4 movement of the templetplate'in an .inward` direction As 'above stated, the templet-plateis provided with a yieldingvertical movement. 1 This is in opposition to the stress of the spring 31.4,.

which surrounds the rod e4, and it ismoved downwardly by the downward movement of.l

the cross-head, as hereinafter explained, and upwardly by the spring el4 upon the upward movement of the cross-head.

The cam-lever el, fastened to the lower end of the post, may be used for the purpose 'of' locking thetemplrt-plate in its lowest position, if desired. i

Astop, F, in connection with the adjustable harf, forming a part of the cross-head frame, controls the extent of the upward movement of the cross-head, and the adjustable stop j" limits the extent of the inward movement ot' the carriage B.

The cross-head C has a frame, c2, extending downwardly and backwardly therefrom,` adapted to slide upon a port-ion of the bracket A', whereby the movement of the cross-head is steadied.

In operation the awls and the templet are brought to the position shown in Fig. 2, and the jack-carriage is moved` to bring-the heel under the templet-plate, as shown in Fig. 1. The lever da is then drawn out and the machine makes one revolution and stops driving the awls through the holes in the templet-plate into the heel and 'withdrawing them therefrom. The operator then revolves the head a third of a revolution, bringing the drivers in position over the heel, substantially as shown in Fig. 4, and the nail-holder, which has been previously filled with nails, is moved into position over the templet and the nails automatically discharged therefrom into the templet and'holes formed in the heel. This stage of the operation is,represented in Fig. 4. The lever d8 is then again drawn out, the machine goes through one revolution, the drivers descend through the holes in the nail-holder and templet, driving the nails intothe heel and soles and clinching their ends upon the metal support. At the same time, by the contact of the driver-holder Gand the upper surface of the nail-holder, the heel is compressed as much as may be desired, the nail-holder and templet moving or yieldingdownwardly with the downward movement of the cross-head and drivers. The operator then revolves the head, and if a top pieceis to be spankedl7 on he moves thear-m c3 into the position before occupied by the awls and drivers, removes the templet and nail- `holder from over the heel, and the lift H having been previously inserted in the springholder h, which is a spring-arm curved to embrace the'side of the liftJ and fastened at It to the arm c3, the lever d8 is again drawn' out, the machine makes another revolution, and the top piece, H, is spanked onto the remainder of the heel.

Of course 1 may use a head having the two arms c c2 without the head o3, if I desire, and

` in lieu of lifting the cross-head by spring-pressure-I may use a positive motion without departing from the spirit of this invention. Having thus fully described my invention, I claim and desire to secure of the United Statesi 1. In an organized heel-nailing machine, the
